IJK 2204-2RS Sealed Self Aligning Ball Bearing 20 x 47 x 18 mm
Available
This IJK range covers 9 double row self aligning ball bearings with two contact rubber seals (2RS): the 2200-2RS, 2201-2RS, 2202-2RS, 2302-2RS, 2203-2RS, 2303-2RS, 2204-2RS, 2304-2RS and 2205-2RS, from 10 to 25 mm bore and 30 to 52 mm outer diameter. Select the size from the drop-down: each size has its own bearing number, dimensions, ball complement and load ratings in the Model Details.
Self aligning ball bearings have a spherical outer ring raceway, so the inner ring and balls can swing to take up small angular misalignment between shaft and housing. They suit long shafts, shafts that deflect under load and housings that cannot be bored in line. The two contact rubber seals (2RS) hold the grease in and keep dust and splashes out.
Where this product is used
- Conveyor pulleys and idler rolls
- Fans, agricultural machinery and line shafting
- Shafts that deflect or housings that cannot be bored in line
Features
- Double row design with a spherical outer ring raceway, so the bearing tolerates small angular misalignment between shaft and housing
- Two contact rubber seals (2RS) hold the factory grease in and keep dust, dirt and splashes out
- Basic dynamic load ratings 7.45 to 18.44 kN and static load ratings 1.59 to 4.71 kN across the range

Selecting the right option
Contact rubber seals (2RS) give better protection against dust, dirt and splashes than shields and hold the factory grease in. The seal lips add friction, so a sealed bearing runs slower than an open or shielded bearing of the same size, and a high speed application is better served by an open or shielded bearing.
Fitting and use
Check the load against the figures for your size before ordering and apply a suitable safety factor. Self aligning bearings carry radial load and a light axial load in either direction, and the misalignment they accept is small, so heavy axial loads and large deflections should be checked with AIMS before ordering.
Press on the ring that is being fitted, not the other ring or the balls: force goes through the side face of the inner ring on a shaft and through the outer ring in a housing.
Sealed bearings are greased at the factory. Do not wash them or heat them before mounting.
